Published by Mark Smith-HalvorsenThere were fresh warnings yesterday (April 29th) that unless David Cameron performed strongly in the televised election debate, sterling would fall this morning.Both the YouGov and ComRes instant polls for the event cast Mr Cameron as the winner, while Nick Clegg took second place.Prior to the debate, a BNP Paribas report warned that forex dealers would sell the pound if the prospect of a hung parliament still looked likely at the close of the debates.The Times reports that the French bank also said the pound would come under worse pressure than the euro after the downgrading of Spain's debt rating, as this would turn attention to the strength of the UK's debt-burdened economy.Gordon Brown once more placed third in the debate last night, despite the focus on the economy, which is ostensibly his strongest card. He repeatedly warned that both Mr Cameron and Mr Clegg are too inexperienced to lead the country through a recovery.For more information on foreign exchange treasury services and risk management, visit our Corporate FX site
